Glycolysis steps provided: Were here now and we’re just getting started, Embden- Meyerhoff- Parnas knew enough to sound retarded=biochemistry scientists who are highly regarded but let’s take up the problems here’s a story, hear to solve em. IT all goes back to when I stole the cake I didn’t mean to take ish but I had to fake-my body into feeling like it made no mistake, here’s the glucose now, where’s the hexokinase? Enzymes are fluid are not druid are you sure you can handle two if I haven’t concluded who you is, if you’s not stupid or being ruthless, add a phosphate from ATP we’ll call yourself cool kid. glucose right here with a phosphate at the six, can you tell that its the end product of gluconeogenesis? I assume you can, but lets say you cant , what you gotta do is shove this rhyme in your pants. G-6-P isomerase makes the next move faced after the change made earlier by hexokinase. It takes the g-6-p and converts it to fructose, with the phosphate at the six the race becomes too close Hold up now cuz you must consider we deal with glucokinase when we’re in the liver. The induced fit enxyme with a Km much quicker hexo- and glucokinases irreversible rivers it’s known that only hexokinase can be controlled by G-6P-and so we’re told-allosterically hindered and consoled. pancreas matches liver process zis story unfolds The product of the reaction is just a minor faction fructose-6-phosphate becomes the major attraction to phosphofructokinase an unsettling foe who …

Description:
The mRNA levels of three antioxidant genes, Cu/Zn superoxide dismutase (SOD), catalase (CAT) and phospholipid hydroperoxide glutathione peroxidase (GSH-Px), were quantified with real-time qRT-PCR in liver of Atlantic salmon Salmo salar exposed to 80% (normoxia), 105% and 130% O”2 saturation for 54 days. The salmon were then translocated and exposed to 90% and 130% O”2 saturation for additional 72 days during smoltification. TBARS and vitamin E levels in liver and the levels of oxidized glutathione (GSSG), total glutathione (GSH) and the resulting oxidative stress index (OSI) in blood were quantified as traditional oxidative stress markers. No significant mean normalized expression (MNE) differences of SOD, CAT or GSH-Px were found in liver after hyperoxia exposure at the two sampling times. Significantly decreased OSI was found in smolt exposed to 130% O”2 saturation after 126 days (n=18, P<0.0001), indicating hyperoxia-induced oxidative stress. No effects were seen on growth, or on the levels of thiobarbituric reactive substances (TBARS) and vitamin E in liver after the exposure experiment. Overall, the mRNA expression of SOD, CAT and GSH-Px in liver related poorly with the hyperoxic exposure regimes, and more knowledge are needed before the expressed levels of these antioxidant genes can be applied as biomarkers of hyperoxia in Atlantic salmon.
